<span>Given that triangle
NLM is reflected over the line segment as shown, forming triangle ABC.
When a point is refrected across a line, the relative distance form the point to the line of refrection is preserved. That is the distance from the point to the line of refrection is equal to the distance of the image to the line of refrection.
Thus, from the figure, it can be seen the point B is of the same distance to the line of refrection as point M, so is point A to point L and point C to point N.
Thus, </span><span>ΔNLM is similar to </span><span><span>ΔCAB
Therefore, the</span> congruency statement that is correct is ΔNLM ≅ ΔCAB</span>
If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds. The z-score for 173 pounds is given by: Referring to a standard normal distribution table, and using z = 0.66, we find: Therefore The answer is: 0.2546
